Sustainable biodiesel is defined as biodiesel that was produced
from waste vegetable oil (WVO), organic crops, or non-crop sources.

Creating biodiesel from plants that are not grown organically
could potentially offset the environmental benefits biodiesel promises due to
pollution from pesticides, herbicides, and insecticides, soil loss, habitat
destruction, and, especially with soy, damage caused by growing
genetically-engineered plants. In addition, biodiesel created from food-based
plants or from plants that replace food-based crops increases the price of food
globally*.

What is Biodiesel?

Biodiesel (B100) "methyl esters" is an alternative fuel made
from natural, renewable sources, such as new and used vegetable oils and animal
fats, for use in any diesel engine.

Blends of biodiesel are noted by the percentage of biodiesel in
the blend of base petro-diesel. B20 means there is 20% biodiesel to the 80%
petro-diesel base. B99 means there is 99% biodiesel to the 1% diesel base. B100
is the pure product and does not contain any petroleum products. Biodiesel is
also an excellent lubricant and can be used as an additive to low sulfur
petro-diesel or as a strong, non-toxic industrial cleaner. While biodiesel and
petroleum diesel are comparable in terms of torque, horsepower, and energy
content, i.e. the number of miles per gallon, B100 biodiesel is non-toxic and
biodegradable.

Why Use Biodiesel?

Petroleum contains more than 40 cancer-causing chemicals and
diesel emissions specifically accounts for 70% of all airborne cancer risk in
the United States, according to the EPA and CARB. Biodiesel (B100), when used in
a diesel engine instead of petro-diesel, eliminates particulate matter (PM) by
60%, PAH (polycyclic aromatic hydrocarbons) by 80%, and nPAH (nitrated PAH's) by
90%. Nitrogen Oxides (NOx) emissions are not reduced, though a thorough study by
the National Renewable Energy Laboratory (NREL) found that NOx emissions do not
increase with biodiesel at any blend level.

Since biodiesel largely originates from plants such as soy and
canola (rapeseed), which absorb CO2 during their lifecyle, the fuel itself is
considered carbon neutral. Every gallon of petroleum diesel, on the other hand,
emits 2.2 pounds of CO2, further contributing to global warming. In addition, On
February 3, 2010 the Environmental Protection Agency's (EPA) issued the final
rule to implement the expanded Renewable Fuels Standard (RFS2). This law
requires that 1.150 billion gallons of biodiesel must be used domestically by
the end of 2010. In this rule, the EPA stated that biodiesel produced from
domestic feedstock is assumed to reduce GHG emissions by 57% compared to
petroleum diesel fuel, and could be as high as 85%.
